The principles of passive solar heating, such as basic types of systems, their description, and the components making up any passive system are presented in this course. Sources of data for heating requirements and available solar radiation throughout the …

Biofuels is one of the Administration’s near-term strategies to address energy security and climate change. In his 2006 State of the Union Address, President Bush declared that America “is addicted to oil” and rolled out the Advanced Energy Initiative …

The 1972 legislation known as the Clean Water Act set secondary treatment as the required level of treatment to be provided by domestic wastewater treatment plants in the United States. In this course you can learn about the basic processes used in …

This course is about measurement of the flow rate of a fluid flowing under pressure in a closed conduit. The closed conduit is often circular, but also may be square or rectangular (such as a heating duct) or any other shape. The other major category of …

Fuel cells are not just laboratory curiosities. While there is much work that needs to be done to optimize the fuel cell system (remember, the gasoline internal combustion engine is nearly 120 years old and still being improved), hydrogen fuel cell …

Many examples of open channel flow can be approximated as uniform flow allowing the Manning equation to be used. Non-uniform flow calculations are needed, however, in some open channel flow situations, where the flow is clearly non-uniform. The concepts …

A weir is basically an obstruction in an open channel flow path. Weirs are commonly used for measurement of open channel flow rate. A weir functions by causing water to rise above the obstruction in order to flow over it. The height of water above the …

Flow of a liquid may take place either as open channel flow or pressure flow. Pressure flow takes place in a closed conduit such as a pipe, and pressure is the primary driving force for the flow. For open channel flow, on the other hand the flowing liquid …
